Filed April 5. 1929 Patented Feb. 24, 1931 PATENT OF CE? D VID J. McE-WAN, or WILMINGTON; DELAWARE HINGE.

Application filed April 5,

This invention relates to hinges and has for an object to provide a hinge which is especially adapted, though, of course, not exclusively confined to use, for hinging the grating employed in the bottom of refrigerator cars supporting the merchandise spaced away from the fioor of the car itselffor C11? culation. y

It is well known thatin such construction 1 1 it is deemed necessary to lift the grating for principle.

the purpose of cleaning the bottom of the car under the grating, and numerous hinges have been devised for the purpose, all of which I show weaknesses either in use or in basic The present invention is directed to a hinge which is exceedingly simple and, therefore, cheap and economical to install and one which will permit the grating to be reused in the usual manner upon the hinge as a fulcrum or to yield to any obstruction which may accidentally be placed under the grating in the process of conditioning or loading the car. a

A further object, therefore, is to provide a hinge having one part rigidly connected with the car body and a second part rigidly connected with the grating, but providing a means whereby the grating is enabled to 3117' move not merely upon the hinge as a fulcrum but independently of such hinge and in a vertical direction. p

WVith these and other obgects 1n view, the invention comprises certain novel parts elements, constructions, interactions, mechanical movements and functions as disclosed in the drawings together with mechanical and functional equivalents thereof as will be hereinafter more fully described and claimed.

Figure elis a top plan view of the hinge in position. l

Like characters of ref rence indicatecorresponding parts throughout the several views. i

lhei1n1')roved hinge which forms the sub jcct matter of this application is adapted to be connected with a car body represented in the drawingsby the side walls Aandfloor- 13, the latterbehlg provided with the usual metal gutter C. 1

Associated also with the car bodyis the usual and ordinary grating comprisingthe stringer D which normally extends throughout approximately"half thelcngth :of the car and the slats E which normally extend throughout substantially half the width of the car.

The hinge itself comprises an upright plate-like portion 10 having a foot 11' adapted to be securedrigidly to the floor B, andan car 12 adapted to be attached rigidlyto the side A of thc car. The car 12 is carriedon an overhang 13 which spaces the plate 10 and foot 11 sufliciently away from the side wall to accommodate the gutter C.

The plate 10 is proportioned to stand above the flooi li of the car substantially to the height of the grating, consisting of thestringerD and slate E, and adjacent its uppercnd provided with an integral or rigid pintle 14.

The second and only other member of the hingecomprises an elongated loop member 15, the inner recess of which is )roperlyproportioncd toslide over and upon the pintle 14c. The loop member 15 is provided with a rigidly connected or integral bolt16, properly proportioned: and positioned to extend througlrthestringer Das shown more particularly at Figuresl and 2 andis'securcd theretobymeans of a nut 17. Vashersi 18 areenniloyed whichmay be transferred from one side tothe other of the stringer Das'mav bed-found necessary or desirable to; provide the proper clearance oft'he grating relative to the carstructure. it

The combinedthickness of theplate 10. and r i the loop 15 is substantially equivalent to. thm

(if: i

themselves prevent the hinge from coming apart and require no means for holding thetWo sections together. While the grating as such forms no part of the present invention, being the usual and ordinary grating standard in such equipment, it does perform a function as holding the hinge in proper'hinging and sliding relation and, therefore. func- Y tionally at least co-acts with and forms a combination with the hinge.

It is believed that the operation will be perfectly apparent, but it maybe explained 7 that in the conditioning of cars it is necessary to raise the gratings. to permit access beneath the gratings for sanitary purposes and that it not infrequently happens that some material or obstruction is left by careless workmen in such position that the-gratings when again returned to floor covering position may be raised at some point above thenormal level which may not be noticed instantly. The present, hinge, therefore, comprisingthe loop member rigidly attached to the grating adapts itself tolift as shown at Figure 2rto accommodate such obstruc-,

tion WltllOlltiIl anyway damaging thehinge which still functions as a hing irrespective of such obstruction. V .What I claim to be new is 1.- A. hinge comprising a pair of rigid members, one comprising a plate having a later- 7 I ally oifset pintle at one side, and laterally offset fastening members at the side opposite the pintle,,the other member comprising'a loop properly proportioned to slide upon the pintle and having a rigid offset shank adapted to be inserted through an article, and a nut upon the shank. V

2. A hinge member comprising a rigid 40 plate, means carried by the rigid plate ofi'set from one side adaptedto attach to a rigid body, a pintle offset from the side of the plate opposite the fasteningem'embers, a loop slid I able upon the pintle,in combination with a grating attached to the loop and having slats spaced at proper intervals to maintain the hinge members in operative union.

3. The combination with a body. member embodying a side wall, a floor an d a gutter in V the floor adjacent the side Wall, of'a'hinge member comprising a plate,'means laterally offset from one side of the platefor securing the plate to the side wall and to the floor and' spanning the gutter, a pintle offset from the plate on the side opposite the fastening members, aloop properly proportioned to slide upon the pintle, a grating having a stringer, means carried by, the last mentioned hinge member for attaching rigidly to the stringer, and slats carried by the stringer properly spaced to and embracing the combined hinge members and holding them in "operative union. 1.

In testimony whereof I atfix my signature.
